I was working on a program in Eclipse. I went to run it, and ran into some 'unknown source' errors, so I tried to reinstall my java and ran into some annoying errors. First thing I ran into was an error saying that Z: is an invalid drive during the uninstall of the JRE.
I used to have a Z partition on my drive with some stuff installed to it, but that has since been changed. I tried again, and ran into a 1723 error, which from what I've found is a problem with the Windows Installer. I'm running Windows 7 and haven't found anything so I can reinstall it. I ran into the same 1723 error when trying to install java over top of the failed uninstall. Any ideas?
